It’s Scott Lang’s kid, Cassie, originally played by Abby Ryder Fortson, last seen played by Emma Fuhrmann in Avengers: Endgame, and soon-to-be played by Kathryn Newton (Freaky, Detective Pikachu) in Ant-Man and the Wasp: Quantumania. We’ve seen her grow up in the movies (well, after a time jump), so it’ll be likely she’d be included in the MCU version of the Young Avengers. Just give her access to Pym Particles, and boom, new heroine.
WandaVision introduced us to Wanda Maximoff’s twin sons that aren’t real but could be real and … It’s just complicated, watch the show.

Since, according to the post-credits of WandaVision, Wanda seems to be on the hunt for them in some form or fashion, we may see some teen versions of them from an alternate dimension or timeline, their souls transported to the bodies of other boys, or some other comic book method to bring them back that Sam Raimi might need to explain in Dr. Strange in the Multiverse of Madness.
Speaking of that movie, Xochitl Gomez was cast as Young Avengers’ America Chavez for Multiverse of Madness. It’s an appropriate debut since America can literally punch and kick star-holes into other dimensions!

Arguably, the most intriguing addition to the team could be Iron Lad. No, Tony Stark didn’t have a secret son (unless they retcon the origins of that one kid in Iron Man 3). In the comic books, Iron Lad was a younger version of this guy:

In the comics, Iron Lad was the person who brought the Young Avengers together to prevent himself from becoming the future version of himself, Kang the Conqueror. Having a young variant of He Who Remains as the person who brings together all of the young heroes to fight off against other eviler, more conquerorier versions of himself would fit within the next Phase of the MCU perfectly.
